Dave,
It's funny that I anticipated the Xara logo bitmap fill and line on the edge of the export! I think we've all been through those before. Something else to watch out for is that the bitmap fills can be linked together. If you make a bunch of rectangles and apply a bitmap fill to all of them, they all will have the default Xara logo. Then if you change just one of them, they all will change, so you have to make them one at a time. I've done it where I tried making a bunch of thumbnails with a bitmap fill and all were linked together. I had to go back to each one and make it a flat fill first before changing to a bitmap fill. Lots of extra work on my part, but it's something that can be useful when you need it.
Good luck and have fun!

Jim
